/* Flag indicating version 3 binding to the PDB.
* while marshalling return values from PDB:
* - not wrap solitary values in list
* - bind c boolean to scheme truth values
*
* Set by a script calling (script-fu-use-v3).
* Cleared by a script calling (script-fu-use-v2).
*
* Initial, default state of all ScriptFu tools is interpret v2 dialect.
*
* New-style scripts call (script-fu-use-v3) at top level.
* Ends with process termination of the interpreter.
*
* Old-style scripts call in run function, but this is discouraged.
* Ends after extension-script-fu finishes interpretation of current command.
*
* Affects interpretation for the duration of the current interpreter process.
* !!! All script interpreted subsequently in the current process,
* especially in called PDB procedures that are themselves scripts,
* must use v3 binding to PDB.
* Note most old script plugins in the PDB use v2 that is affected by this flag.
* Note a very few routines in script-fu-util.scm call the PDB using v2 binding.
* So a script should not call them while this flag is set.
